IPC: B61F5/10
Filed: 1993-09-13
Abstract: PURPOSE:To forcibly tilt a car body under the specified conditions when it passes the curved track. CONSTITUTION:In a railroad rolling stock controlling a car body 1 by the vertical expansion/contraction of each air spring of front and rear trucks, a laminated rubber 4 having the buffering ability against the vibration in the right-to-left direction is provided between the air spring 3 and the car body 1 so that the upper surface of the air spring 3 may bring the car body 1 under tilt control in the direction orthogonal to the resultant force of the gravity and the centrifugal force exerted on the car body 1 when the car body 1 passes the curved track. This constitution improves the comfortableness without deteriorating the vibration damping in the lateral direction to cause the striking of the right and left stoppers.

Abstract: PURPOSE:To print and record telephone charge receipt/request information, etc., by providing a means which prints a bit of information from an external information processor inputted through a telephone line. CONSTITUTION:Firstly, an individual personal identification number ID proper to the owner of a telephone set is inputted from a host computer to a telephone set main body 6. the above signal is inputted from the main body 6 to an ID detector 8 via a two-way converter 7. The detector 8 judges whether the individual personal identification number in a storage circuit coincides with the ID from the converter 7, and when coincidence between them is obtained, it outputs a coincidence signal. The coincidence signal is sent to the host computer via the main body 6, and also, it is inputted to the power source control circuit 9 of a printer, thereby, a power source is turned ON. And, since the host computer sends print information required for the telephone set side, for example, the telephone charge receipt/request information, the main body 6 side inputs the information to a memory control circuit 10, then it is printed and recorded.
